They are. I have October flights booked with them, and I was originally on the last flight of the day (7:55pm), so I can still work during the day. Well, I decided to check on my seating for the flight last night, and when I went into my account, I had an alert. They canceled my original flight and put me on a 5:35pm flight. No notice at all. They canceled and combined the flights, originally there were 4 nonstops to MCO, now it's only two. This isn't the first time I've had this happen with JB. I'm not happy, but it is still better than some of the other options. And I'm sure it will change again before October!
